City signed Haaland, 21, the top scorer of Borussia Dortmund, earlier this week, to move to the Etihad Stadium following the end of the season.
The former Barcelona and Bayern Munich coach is seen as a major player in attracting elite players to his clubs.
“The players come here not for me, but to play in this competition and to represent this club,” he told reporters before facing West Ham United in the Premier League on Sunday.
“It is very important to think regarding the people, the way of playing, the size of the team, the city, the competition, the expectations of playing in the Champions League in the coming seasons, many things that influence,” he added.
Guardiola gave examples of former stars in the team such as Sergio Aguero, David Silva and Vincent Kompany, who stayed at City for nearly a decade and achieved great success with different coaches.
“Players don’t come for a month or a year, what we do is to make them happy in the city and in the dressing room and enjoy playing in the Premier League.”
City need four points from the last two games to win the league title for the fourth time in five years.
